We are part of an umbrella organization that offers classes every other Wednesday for 3 hours (PE, Geography, and Art). The umbrella is slightly different than a coop. An umbrella takes the place of reporting to the state (in our state that is). And, they offer screened teachers. If you can't find a good coop, perhaps you could look into an umbrella organization. Our state lists them on the homeschooling section of its website.
